Features used to implement the example

• Write field on linked issues or sub-tasks
• Virtual fields "Issue status" or "Execute transition": writing into these fields the name of an status or the name of a transition respectively, makes an issue progress through its workflow, provided conditions and validators in the transition are satisfied

Example: Automatically transition sub-tasks to certain status when parent issue is transitioned to another status

We are going to explain how we can automatically move all sub-tasks to a certain status in sub-task's workflow, when parent issue is moved to another status in parent's issue workflow.

In this example we suppose that both parent's and sub-task's workflows have a status called "Cancelled". We want to automatically cancel all sub-tasks when parent issue is cancelled. We also suppose that there is a global transition called "Cancel Issue" in both workflows (parent's and sub-task's) which has as target status "Cancelled".

To implement this use case we insert Write field on linked issues or sub-tasks post-function in transition "Cancel Issue" in parent's workflow, using the following configuration:

Once configured, the transition looks like this:
